Development of refrigerated compartment production technology

Refrigerated trucks consist of three parts: the chassis, refrigeration units, car insulation. 

Refrigerated trucks car body production technology are: the fragmentation assembly "sandwich" plate - bonding, use of this technology with refrigerated trucks insulation properties of green tea is higher, so by many refrigerated vehicle production enterprises of all ages; fragments assembled foamed injection; the whole skeleton injection foaming formula; vacuum suction paste. 

Refrigerated compartment in three stages of technology development: the first stage, the overall metal skin into the foam structure; the second stage, the overall injection foam glass steel; the third stage, closed polyurethane adhesive glass plate steel. The first generation of refrigerated trucks manufacturers have adopted a whole into the foam structure metal skin, the product is easy to form a large number of cold bridges, but also difficult to find defects, does not guarantee the intrinsic quality, not easy to produce high bond floor is not ideal thermal insulation old rate defects. The second stage of the technology is a second-generation and third-generation refrigerated vehicle manufacturers use such products on the basis of the first stage of the product improved on a step, light weight, reduce heat leakage rate, the insulation effect is better, but bond exists not old, trains skin defects such as bubbling and easy. PU closed glass plate steel in the second and third generation refrigerated vehicle manufacturers have also used this tea light quality, missing people yield, good insulation effect, the only point is to cut losses after the polyurethane is relatively large , the cost is relatively high, this refrigerated trucks in the domestic market dominant. 

Refrigerated truck compartment development process is inevitable, with the introduction of foreign advanced technology and its own research and development, defects in workmanship gradually being removed, innovation and continuous improvement to provide basic technical support for the development of refrigerated trucks.
